    I just what to know if the MAC is vintage if contains
a 68000? 
 Consider this, it's been nearly 10 years since a Mac containing a 68000 CPU
 was even able to run the current version of the operating system.  I forget
 if support was dropped with System 7.6, or Mac OS 8.0. 
 8.5. 8.0 dropped the '030 and prior, but an '040 could still run 8.0 and 8.1
 officially, and an '030 could run them with some hacking. 
Was that due to instruction set differences?  Stack frame differences?
 MMU differences?
